Dremel 225 Flex-shaft - Multi-Purpose Flexible Shaft Extension for Dremel Rotary Multitools

I purchased the Bosch 'Dremel' sometime ago. Whilst both companies share a parent, it's not made clear in any of the Dremel documentation whether this tool is compatible with the GRO.I can confirm that it is. Works perfectly, allowing access to areas where there would otherwise be obstruction from the large body of the Bosch tool itself. The only thing to note is that, unlike Dremel brand rotary tools, the Bosch lacks a hanger loop to support it, used to keep the flexi-drive within its working bend radius. I fix mine in an old lab clamp/retort stand whenever the work I'm doing doesn't allow for one handed working. It is necessary to hold the 'powered' end, due to the rotational reaction in the cable - it would otherwise try to move around.Meets expectations for Dremel quality and great value.

Amazing quality from dremel, comes with everything you need to attach toy your dremel and make it easier to use for precise work

works fine

Bought for my son in law, useful extra.

Excellent piece of kit

Give it a 5 star becouse it looks well made not tested yet but looks great not sure on speed yet but sure it looks fine

Good value for money, quality seems good, light and functional. Seems to fit the Dremel correctly

This arrived next day - thanks to Prime.Included in the package with the flex shaft is a silver hex nut called a "drive cap" . You do not want to lose this, as it is the "key" to making the flex shaft work properly. Get a 35mm film container or similar, label it "Drive Cap 225" and put it in your DREMEL case.To install the 225, first, remove the collet and the collet nut from the DREMEL Tool and set them aside. Then, unscrew the nose cap from the Tool. Set this aside as well.Take the drive cap and put it on the collet thread of the Tool. Run it down, finger-tight, and then, using the DREMEL wrench, just give it a tweak to the left, just to nip it up.Insert the drive cable of the 225 into the drive cap. Then attach the black collar of the flex shaft to the thread where the nose cap of the tool used to be.The collet and the collet nut from the Tool now go into the handpiece of the 225. Put the nose cap of your Tool in the same safe place as you will later put your drive cap. You will want to be able to find this if you ever want to take the 225 off.Hang the Tool up so that the flex shaft is vertical. Set the Tool to its lowest possible speed and turn it on. Let it run on its own for 1 to 2 minutes. This will work out the kinks and distribute the factory lubricant along the sheath of the flex shaft.After this is done, you are ready to let rip up to 35,000 rpm.The 225 works at its best when operating at either a vertical or an horizontal position. Yes, the shaft is flexible, but it is not infinitely so. Over-bending it will either cause hand-piece bearing failure or breakage of the drive cable. Heat in the handpiece and/or at the tool/shaft junction may indicate over-bending of the shaft or a need for lubricationAs a general rule, I work with my tool overhead (vertical) and with the coupling (Tool-225) at head-height, whether standing or seated. This allows a gentle transition from the vertical to the horizontal as I work.I usually work standing: better controlFor vertical applications, there is the DREMEL 220-01 WORK STATION which I already have. The Work Station will also work in horizontal mode.The Flex Shaft needs to be lubricated after 7-10 hours of use. In my case, this means routinely every week, as I use mine a lot. Here's what I do:Get some lithium high-temp wheel bearing grease. (I use the comma grease available here on Amazon) You do not need much, trust me, a tub will last you for an age.Hang the tool up . Pull the drive core out of the 225.Take a blob of grease about as big as the ball of your little finger and wipe it all the way down the drive core.Flip the core over, end for end, and then run it in again for a minute or two on the slowest speed - this will distribute the grease.And there you go, looking after it is key to getting plenty of use out of it. I had my last one for several years until it got broken by me under the wheels of my workbench chair! (Careless!)
